I added a force register function and made all of the static variables available to me so I can make them equal NULL so when I retry the things registered would be reset and it still crashes. The things I made NULL are first_hwaccel = NULL; first_avcodec = NULL; av_first_parser = NULL; first_bitstream_filter = NULL;
first_iformat = NULL; first_oformat = NULL; first_protocol = NULL; I'll try looking around in debug to see if I can find any static variables that has to do with that sum variable. I can say that in the debug (from what I remember) the variable sum is 0, I don't know if that could cause it to crash.
